Tagging for later. Have lots of advice to give, but can't tell you now as I'm too busy at work.

That's why I wanted to go into my first year undecided, just to have some opportunities open, however, for me, I'm not too worried about doing history because the part of the US that I live in in constantly building new schools so the job market for teachers is actually quite good where I live, and teaching is what I want to do with that degree. 

But thank you for your advice regardless, I'm definitely taking it into consideration.

Bit early isn't it?

It's your chance to start Fresh and have the grades you've always aimed for.

Forget Guys/Girls, connections and grades are all you need.

Most importantly don't be a drone,have your own opinions and be proud of them. 

1. Plan ahead with your elective courses. I did a minor in Finance with mine. Don't waste them on useless courses.

2. Have fun but don't overdo it. Keep a balance with study and social life.

3. If you can, go to the gym. It's a great way to relieve stress and meet other people.

4. Join a club at your university (the more related to your major the better). It's a great way to network with other people inside and out of campus.

5. Don't let things for last. Study and do your assignments with anticipation.

Been studying for a year now. I just got to say that it’s important to work with school every day, but it’s also important to take break with gaming to unstress and disconnect a little.

Also, you’ll get homesick. The best thing to do about it is to do something, anything. Gaming, watch a movie, bake some muffins. The worst you can do when homesick is to sit around and think.

If the career doesn't suit you or you feel off on day 3, change careers...

As a bachelor in history, I'd say read everyday. It is important to get in that reading rythm, as you will get a lot of reading assignments (which are quite too often boring as hell). Also, read more than is acquiered. History is about understanding, not just repeating what they tell you. Get some texts or books about the same subjects but with different theories and try to position yourself in that debate. Every generation rewrites its own history, so don't be reluctant to pick up some oldtimers like Huizinga, von Ranke, Febvre, Bloch etc... (you will probably have to read them anyway), to really understand the tendencies of history. You won't get through History in college if you don't have passion for it and like to write (and re-write).

As for the dorm, I have no clue. I just reside in an appartment near the citycampus.

I agree. I've got teachers in my family.

I'm not saying that it's the case of our OP, but many have a romantic view of school teaching. The truth is: it's babysitting. The students are your boss, there's no discipline, they don't want to learn, they don't see the point in learning, parents defend them more than the teachers. Unless you're going to teach in a military school or in a upper class boarding school, you're just a babysitter.
